Ten hikers were found parched in Modjeska Canyon on Wednesday as they trekked in high temperatures to prepare for a climb of Mt. Whitney, officials said.
The group, comprising business executives from Los Angeles, Orange and San Diego counties who were not identified, began their hike about 6:30 a.m. from the Harding Truck Trail in Modjeska Canyon, officials said.
They hope to scale Mt. Whitney, the tallest peak in the continental United States, in the fall, said Capt. Stephen Miller, spokesman for the Orange County Fire Authority.
About 4 p.m., one hiker, suffering from heat exhaustion, returned to the trailhead and called for help. He was treated at the scene as an air and land search was launched to find the other hikers.
